Call up 3gstore.com and ask. So far no one here has noted any difference among the cards.
I'm trying to decide which air card would be best for online gaming purposes, and I'm going to go with the Verizon Wireless Network. Does anyone have any suggestions? I have a UM150 right now, but before I go and get the appropriate router I am going to make sure that my card will or will not do the job.
